Accepted answer
var vm = new Notification();
The above line means instantiation, so it will always be null, it is very obvious.
you will get the value in the notificationMenuDataModel parameter only.

You need to debug that line and can check why null is coming. From here it is difficult to tell why null is coming as you already set value. Thanks
